PHP while loop separate from every 2 rows into a div - php

Question

I have a while loop from database, but i want to wrap every 2 rows into a div.
Currently i have this but is only wrapping first row.
<?php
$get = $connect->query("SELECT * FROM sabiaque ORDER by ordem");
$num = 0;
while ($f = $get->fetch_array(MYSQLI_ASSOC)) {
if ($num % 2) {
echo '<div class="divisor-slide">';
}
echo'
<a href="'.$f['link'].'"><div class="item-a">
<div class="box1-item-a">
<div class="i-wrap"><h1 class="i-white">'.utf8_decode($f['titulo']).'</h1><p>'.utf8_decode($f['subtitulo']).'</p></div>
</div>
<div class="box1-item-b">
<img src="../'.$f['ficheiro'].'" style="max-width: 100%; height: 100%;" />
</div>
</div></a>
';
if($num % 2) {
echo '</div>';
}
$num++;
}
?>

Answer 1

change this :
if($num%2) {
echo '<div class="divisor-slide">';
}
By this :
if( ($num % 2) == 0) {
echo '<div class="divisor-slide">';
}
And this :
if($num %2) {
echo '</div>';
}
To :
if( ($num % 2) == 0) {
echo '</div>';
}

Answer 2

I often find I get into a muddle using these special $num%2 whatsits (I'll get all excited in being clever in using them, then forget later what they do when I revisit the code). Why not simplify it like this (although it uses a little more code):
$num = 1;
while ($f = $get->fetch_array(MYSQLI_ASSOC)) {
if ( $num == 2 ) echo '<div class="divisor-slide">';
// rest of code
if ( $num == 2 ) echo '</div>';
$num++; if ( $num == 3 ) $num = 1;
}
